Description

Split gusset connection

This application claims priority to US Provisional Application No. 61/442,738, filed February 14, 2011, the contents of which are incorporated herein by reference.

background

The present invention relates generally to structural joints, and more particularly to a gusset plate connection that allows greater relative movement between connected structural members and simplifies construction on site.

Figure 1A shows a typical gusset plate connection in a frame support structure in the prior art. Horizontal structural members Bm (beams) are connected to vertical structural members C (columns). To connect the diagonal structural member Br (ie brace) to the beam-column assembly, gusset plate G is used. The braces are connected (by eg pins, bolts) to the gusset plates, which are then usually welded to the beams and columns. The length _Lcc is the clear length of the column C between the two ends of the gusset plate G, and the length _Lbc is the clear length of the beam Bm between the two ends of the gusset plate G.

The gusset plates of the prior art can be welded to the beams and columns, the improvement of which produces a fixation so that relative movement between the beam Bm and the column C is impossible. In practice, this results in large internal forces locally in the beams and columns. Figure 1B shows the respective bending moments M _b /M _c in beam Bm and column C, and the respective shear forces V _b /V _c in beam Bm and column C, which are obtained using bolted connections / Welded results of the structure of the gusset plate G. The bending moment M _br and shear force V _br supporting Br are also shown. Figure 1B shows the configuration of the bolted connection between the beam Bm and the column C, and as shown in Figure 1C, the same stresses occur in the welded (and welded and bolted joint) configuration.

The shear force V _b is proportional to the bending moment M _b and the net length L _bC of the beam (ie V _b ∝ M _b / _bc ). Likewise, the shear force V _c is proportional to the bending moment M _c and the net length L _cc of the column (ie, V _c ∝ M _c /L _cc ). Strengthening the joint by increasing the width and height of the gusset plate directly shortens the net length of the beam L _bC and the net length of the column L _cc , which in turn acts upon the same bending moment M _b imposed on the structure by external forces (eg, wind, earthquake, etc.) And M _c makes the shear force V _b and V _c become larger. In extreme cases, these large internal forces can break beams, beam-column bolted/welded structures, columns and/or gusset plate welds if prior art connecting components are not designed accordingly. However, if all prior art connecting parts are designed to withstand large internal forces, the weight, material requirements and costs of the structure will increase significantly.

Contents of the invention

An embodiment of the present invention provides a structural node. The vertical column may have a first gusset plate portion. A horizontal beam can be connected to the vertical column. The horizontal beam may have a second gusset plate portion that is not directly connected to the first gusset plate portion.

A horizontal beam may be fixedly connected to the vertical column at the node location. The horizontal beam may have a second gusset plate portion fixedly connected to the horizontal beam. The second gusset plate portion may be spaced apart from the first gusset plate portion at a node location. The braces are movably connected to the first and second gusset plate sections at node locations. The brace may be articulated to the first gusset portion by a first articulating connection. The brace may be articulated to the second gusset portion by a second articulation. The first and second articulations are separable from each other.

Detailed ways

Particular embodiments of the invention include gussets that add minimal stress to all components to which they are attached, such as beams and columns. In this case, beams, columns and braces experience a minimal increase in their stresses by adding our gusset plates. Thus, the advantages of prior art gusset plates (enabling support beams to be coupled to column and beam joints) are maintained, while the detrimental force (due to large earthquake-like forces) transfer properties of prior art gusset plates are largely eliminated. Therefore, for structures with beam/column/bracing joints, when an external force (e.g., seismic force) is applied, the gusset plate of the present invention will not transfer the motion of the beam to the column, the motion of the column to the beam, and the brace The motion of the gusset plate is transferred to the beam and/or column, whereas a standard gusset plate connection would. Thus, without the gusset plate of the present invention, the transfer of forces between the columns, beams and braces would occur, but would resemble a true dynamic load at the work point connecting all three members. In some embodiments, the gusset plate of the present invention may also itself have less stress than prior art gusset plates. All of these advantages are achieved by allowing greater relative movement between the connected members using the gusset plate connection of the present invention.

Particular embodiments of the present invention provide gusset plates for connecting column, beam and diagonal support members in steel frame buildings. The gusset plate allows the columns and beams to hold and support the diagonal struts for triangular loads, as is normally expected with standard prior art gusset plates. In addition, gusset plates allow column, beam and diagonal braces to move independently of each other when subjected to extreme dynamic loads, which may be the result of strong winds or earthquakes, and may also cause prior art joints to fail .

Thus, in contrast to prior art gusset plates, the gusset plate of the present invention does not transmit (significant) movement of the beam to the column and vice versa, and thus the gusset plate does not amplify and/or transmit dynamic loads. For example, a sway moment acting on a column would expect it to move, and to some extent, to a beam connected to it, whereas the gusset plate of the present invention does not transfer sway moments to the beam and thus does not amplify the The effect of the movement induced by the technical gusset plate. The gusset plate of the present invention may comprise a first gusset plate portion movably or fixedly connected to the column and a second gusset plate portion movably or fixedly connected to the beam. These gusset plate sections are not directly connected to each other, but are movably, fixedly and/or rotatably connected to the diagonal struts.

As used herein, "movably connected" or "movable" or "mobile connection" is understood to mean a connection between two or more structural There is horizontal and/or vertical relative movement between components. Such connections generally do not allow movement under static loads or generally dynamic loads (eg as imposed from light/moderate wind forces). With respect to the prior art bolted gussets, "movably connected" should be understood as allowing movement well beyond borehole tolerances. An example of a movable connection is a fixed bolt in the slot, which is fixed so as not to move under static or normal dynamic loads, but movable in the slot under extreme dynamic loads. Therefore, the slotted bolt connection described here should be understood as a movable connection. It should also be understood that where a slotted connection is disclosed, only one of the connected parts (eg, gusset, brace) needs to include the slot to provide a movable connection. However, in some embodiments, at least one or all of the connecting portions include elongated slots that provide a movable connection.

As used herein, "fixedly connected" or "fixedly connected" or "non-movably connected" is understood to mean that a connection between two or more structural members is not configured to provide relative movement (beyond provided by prior art bolted gussets). An example of a fixed connection is a welded joint or a bolted connection, and in some cases welded seams and bolted connections. To some extent, the bolt hole tolerance may allow limited movement, however under high loads this may or may not occur and will of course be limited, thus ultimately resembling a welded connection. Therefore, welded joints and bolted joints (without slots) described here should be assumed to be fixed joints.

As used herein, "rotationally connected" or "rotatable connection" or "rotational connection" is understood to mean a connection between two or more structural members which permits rotation between the members relative movement. An example of a rotatable connection is a pin connection. Therefore, the pin connection described here should be assumed to be a rotational connection. However, a gusset plate assembly with pins located within the gap would allow rotational, horizontal and/or vertical relative movement.

"Force" or "earthquake-like force" or "potentially destructive force" as used herein is understood to be a dynamic force exerted on a building structure from the outside which far exceeds that exerted by intrinsic building loads through conventional wind and movement dynamic load. Such forces may be exerted by earthquakes, hurricanes, tsunamis, and the like.

Figure 2A illustrates beam-column-braces connected by gusset plate assemblies 200, according to a specific embodiment of the invention. The gusset plate assembly 200 includes two gusset plates 200a/200b separated by a gap. The gap will be wide enough to provide sufficient free movement of the two gusset plates 200a/200b without collision. In some embodiments, the width of the gap ranges from 12mm-300mm, or more commonly, between 25mm-100mm. The gusset plate 200b is fixedly connected to the beam Bm by, for example, welding it, and similarly the gusset plate 200a is welded to the column C. The brace Br is bolted to the two gusset plates with a plurality of bolts 202 . Typically, the columns C, beams Bm and braces Br are prefabricated structural members such as I-beams or tubes. It should be understood that the term "bolt" is meant to include various fasteners such as bolt/nut combinations, screws, rivets, and the like. The gusset plate 200a/200b may be fabricated from a high strength material such as steel plate or composite material. The thickness and other dimensions of the gusset plate 200a/200b can be obtained in the same way as the prior art gusset plate according to the requirements of the specific structure to be built.

A plurality of bolts 202 are movably connected in slotted bolt holes 204 of the gusset plate 200a/200b and the brace Br. When installed, the slotted bolt holes 204 are perpendicular to the centerline of the gap G as shown, and thus are generally angularly oriented with respect to the structure. In some embodiments, curved slots may be used. The gap and slot 204 allow the gusset plates 200a/200b to move relative to each other. Thus, beam Bm and column C are effectively able to move relative to each other (since they are fixedly connected to the gusset plate 200a/200b) as if the gusset plate did not exist, and thus around the intersection of the centerlines of beam Bm and column C The working point WP1 rotates. The alternate work point WP2 is located where the centerline of the gap G actually intersects the beam Bm and column C joints. This configuration prevents the respective dynamic loads applied to the columns C and beams Bm from being transferred to each other via the gusset plates 202a/202b.

In some embodiments, the bolts are secured to the face of the gusset plate using large washers through oversized holes instead of long slots. A polymer, rubber or soft metal O-ring may be located within the oversized hole to help center the bolt and/or absorb shock, vibration and force. The bolts in the elongated slots 204 can be tightened to the extent that connections according to the prior art can be made, and in some cases smaller or larger. It can be expected that earthquake-like forces will be so great that bolt tightness is not a critical factor. When potentially destructive forces are applied to the gusset plate assembly 200, it does not behave in the manner described in FIG. 1A, where the moment-induced shear forces are amplified by the presence of the gusset plate.

In some embodiments, only the braces Br or gussets 200a/200b include slots, while others include threaded holes for bolts to be fastened directly thereto.

One advantage of the present invention is that it is possible to weld the gusset plate 202a/202b to the beam Bm and column C in a workshop (i.e. not at the building site) and to simply install the components on site using the bolts 202 (i.e. at the site at the building site). mounting bolts). The prior art arrangement in Figure 1 requires welding at the construction site, which is less reliable and less precise, less controllable, more expensive, and more time consuming than shop welding. Ideally, the structural elements are as prefabricated as possible and there are almost no structural connections by welding on the building site. For these reasons and others, there is a stronger preference for shop welding followed by field installation of bolts in the construction industry.

Figure 2B shows the same configuration as Figure 2A, with a set of slotted bolt holes 204 on the gusset plate 200b perpendicular to the centerline of the beam Bm, and thus generally vertically oriented with respect to the structure. Another set of slotted holes 204 on the gusset plate 200a is perpendicular to the centerline of the column C, and thus generally horizontally oriented with respect to the structure.

This configuration still allows the relative motion of beam Bm and column C provided in Figure 2A, and can be used to isolate the forces transmitted from support Br to beam Bm and column C. Because the bolt holes 200 in the gusset plate 202b are vertical, vertical movement is allowed (no force transmission) with the bolts on the plate under load, and forces can only be transmitted horizontally. A similar situation exists on the gusset plate 202a, where lateral movement is allowed (no force transmission) with the bolts on the plate under load, and forces can only be transmitted vertically. Thus, the fixed connection (e.g., weld) at beam Bm receives only horizontal force (parallel to the weld), while the fixed connection (e.g., weld) at column C receives only vertical force (parallel to the fixed connection) .

2C and 2D show end views of the gusset plate assembly 200 . As shown, the brace Br may be movably connected to only one side of the gusset plate 202a/202b, as depicted in Figure 2C. Alternatively, as depicted in Figure 2D, the braces Br may be movably connected to both sides of the gusset plate 202a/202b.

Figure 2E shows an embodiment in which only one gusset plate includes elongated slots 204 and the other gusset plate is fixedly connected (eg, bolted and/or welded).

Figures 3A and 3B illustrate an alternative gusset plate assembly 300 to that shown in Figures 2A and 2B, respectively. Here, the main difference between those components is that the braces Br are arranged at an acute angle and thus the gusset plates 302a/302b are not symmetrical about the dividing centerline CL. As shown, the gusset plates 302a/302b are configured such that the separating centerline CL intersects at the operating point WP1. Thus, gusset plate 302a is larger than gusset plate 302b. Alternatively, the dividing center line CL may intersect with WP2 as shown in FIG. 2A in a manner of moving in parallel. This alternate embodiment can create a more central gap between the gusset plates 302a/302b than shown. In all other respects, the gusset plate assembly 300 may be constructed as disclosed with respect to the gusset plate assembly 200 .

Figures 4A and 4B illustrate an alternative gusset plate assembly 400 to that shown in Figures 3A and 3B, respectively. Here, the main difference between those components is that the support Br is arranged at an obtuse angle. As shown, the gusset plates 302a/302b are configured such that the separating centerline CL intersects at the operating point WP1. Thus, gusset plate 402a is larger than gusset plate 402b. Alternatively, the dividing center line CL may intersect with WP2 as shown in FIG. 2A in a manner of moving in parallel. This alternative embodiment can create a more central gap between the gusset plates 402a/402b than shown. In all other respects, the gusset plate assembly 400 may be constructed as disclosed with respect to the gusset plate assembly 200 .

Figure 5 shows a beam-column-bracing joint connected by a gusset plate assembly 500, according to a specific embodiment of the present invention. Here, the brace Br is connected to the gusset plate assembly 500 using a single pin 502 instead of multiple bolts. To accommodate the pins 502, semicircular cutouts are made in each gusset plate 504a/504b along the edge of the gap to accommodate the pins. This connection allows horizontal and vertical relative movement as well as rotational relative movement via the pin 500 due to the presence of gaps that are spaced apart in both directions, horizontally and vertically. In all other respects, the gusset plate assembly 500 may be constructed as disclosed with respect to the gusset plate assembly 200 .

Figure 6A shows a beam-column-brace assembly connected by a gusset plate assembly 600, according to a specific embodiment of the present invention. Here, the gusset plate assembly 600 includes a first stub 602 fixedly connected to the beam Bm by a fixed connection (eg, bolted and/or welded). The second short plate 604 is fixedly connected to the column C in the same manner. The gusset plate 606 is fixedly connected to the brace Br. The first short plate 602 and the second short plate 604 may be constructed from extruded material, such as steel "angle iron". Gusset plate 606 is movably connected to first short plate 602 using obliquely oriented (perpendicular to centerline CL) slotted bolt holes 608 . Horizontal and vertical gaps are located between the edge of the gusset plate 606 and the beam Bm and column C, respectively. Such an arrangement allows the relative motion of beam Bm and column C as described herein, and also provides the added advantage of isolating the forces transmitted from the brace Br to beam Bm and column C.

FIG. 6B shows an alternate configuration for the first short plate 604 and the second short plate 606 of the gusset plate assembly 600 . Here, gusset plate 606 is movably connected to first short plate 602 using vertically oriented slotted bolt holes 608 . Similarly, gusset plate 606 is movably connected to second short plate 604 using horizontally oriented slotted bolt holes 608 .

6C and 6D show alternative configurations in which the brace Br is attached to the gusset plate 606 . Figure 6C shows the brace Br in a bolted configuration. Figure 6D shows that the brace Br is pinned to the gusset plate by a large pin that can rotate.

6E, 6F, 6G and 6H are various configurations for attaching the first short plate 602 and the second short plate 604 to the beam Bm and column C, respectively. Figures 6E and 6F show single-sided and double-sided short plate attachment configurations, respectively, with short plates welded to beams Br or columns C. Figures 6G and 6H show the single-sided and double-sided short plate connection configurations, respectively, where the short plate is bolted to the beam Br or column C.

Figure 7A shows a beam-column-brace assembly connected by a gusset plate assembly 700, according to a specific embodiment of the present invention. Gusset plate assembly 700 is similar to that disclosed in Figure 2A. Here, however, the gusset plate assembly 700 includes a first gusset plate 702 fixedly attached to the column C and a second gusset plate 704 fixedly attached to the beam Bm. The first gusset plate 702 and the second gusset plate 704 are offset from the centerline of the beam and column bisecting the web of the beam and column such that the first gusset plate 702 and the second gusset plate 704 slide past each other in different planes. The braces Br are bolted to the two gusset plates by using slotted holes 706 arranged at an angle (centerline perpendicular to the centerline CL).

7B, 7C and 7D illustrate different configurations of the gusset plate assembly 700 . In FIG. 7B, the first gusset plate 702 and the second gusset plate 704 are arranged as shown in FIG. 7A such that the brace Br is located between them. Alternatively, the first gusset plate 702 and the second gusset plate 704 may be arranged such that one side of the support Br is exposed as shown in FIG. 7C . In such a configuration, both the first gusset plate 702 and the second gusset plate 704 are arranged on the same side of the web of the column C and beam Bm. Alternatively, as shown in FIG. 7D , the first gusset plate 702 and the second gusset plate 704 may be arranged to contact each other on the inner side, and the braces Br are placed on both outer sides.

Figure 8A shows a beam-column-brace assembly connected by a gusset plate assembly 800, according to a specific embodiment of the invention. The gusset plate assembly 800 is similar to the gusset plate assembly 700, but here the gusset plates 802 and 804 are interconnected to the brace Br by physical pins. Oversized holes are made in the gusset plates 802 and 804 which allow the gusset plates to move perpendicular to the centerline CL of the brace Br. Similar to Figures 7B-7D, Figures 8B-8D respectively show that the brace Br can be sandwiched between two gusset plates 802 and 804, or capped on one side of the gusset plates 802 and 804, or that the brace Br has forked ends , two gusset plates 802 and 804 can be sandwiched in the middle.

Figure 9A shows a beam-column-brace assembly connected by a gusset plate assembly 900, according to a specific embodiment of the invention. Figure 9A shows a new configuration of the invention (similar to the embodiment depicted in Figure 6), a gusset plate assembly 900 having three plates. The first plate 902 is fixedly connected to the beam Bm, and the second plate 904 is fixedly connected to the column C. The third (or primary) plate 906 is fixedly connected (welded in this embodiment) to the support Br. The third plate 906 is movably connected to the first plate 904 through slotted bolt holes arranged perpendicular to the centerline of the support Br. The third plate 906 is also movably connected to the second plate 904 through slotted bolt holes arranged perpendicular to the centerline of the support Br. There is a gap between the edge of the third plate 906 and both the beam Bm and the column C. The third plate 906 can be provided as a single plate part bolted to one side of the first and second plates 902/904 so that it only touches one of the first and second plates, or the third The plates may be arranged as two plate sections sandwiching first and second plates 902/904 welded to beams Bm and columns C.

Figures 9B and 9C show alternative configurations connecting the brace Br to the third plate 906 by means of solid pins and bolts, respectively.

Figure 9D shows the same beam-column-brace assembly as in Figure 9A, with slotted bolt holes parallel to beam Bm on the second plate 904 and slotted bolt holes parallel to column C on the first plate . Such a configuration may provide the added advantage of isolating the forces transmitted from the supports to the beams and columns, as shown in Figure 2B.

The specific embodiment of the invention is not limited to the connection of the beam Bm and the column C. For example, Figure 10 shows two different configurations of a gusset plate assembly for attaching a brace Br to the middle portion of a beam Bm (where the two braces Br meet). For simplicity, two different gusset plate assemblies are shown, which may be the case in some embodiments, while in other particular embodiments the construction may be symmetrical. The left hand side shows a gusset plate assembly 1000, which is similar to the embodiment depicted in Figure 2A. The right hand side shows a gusset plate assembly 1010 having a similar construction to the embodiment depicted in Figure 6A.

Here, the gusset plate assembly disclosed in Fig. 2A was used in a column-brace-baseplate situation. It should be understood that all of the gusset plate assemblies disclosed herein may be applied to the column-brace-slab configurations of the disclosed figures where a base plate is used instead of a beam.
